Question

How can I soundproof a server rack?

Answer 1

Answer:

Being an active part of the digital age, we are well aware of how annoying can the buzzing noise from an equipment be. It is even more problematic when we are required to be productive, but the constant sound becomes a hindrance. This noise from active IT equipment in a high-technology workspace can lead to health issues like loss of productivity, work slowdown due to depression, and hearing impairment. Prolonged exposure can lead to serious health issues too.

Soundproof rack is an ideal option to minimize this sound. Switching to an acoustic rack can reduce the noise drastically to a level of 30 dBA. The audibility in an office space can vary anywhere between 48dBA to 78 dBA. So, if a device reduces the noise limit up to 30 dBA, it would mean the sound equivalent to that of a whisper’s level. Designed specifically to get rid of the equipment noise, an acoustic rack is considered the best soundproof server cabinet as they are lined with a fire retardant, multilayer acoustic material within the inner surfaces to achieve a superior level of noise reduction from high frequency noise. Hence, the Acoustic Rack Active from Netrack is a desirable solution for such noise issues.  

Soundproof rack cabinets are also equipped with Active noise-cancelling technology which is highly effective in reducing low-frequency noise. The ASFT (Active Silence Fan tray) in acoustic racks reduces the noise produced by auxiliary fans and installed equipment noise to the surrounding noise level

ANSWER

In order to soundproof a rack, it needs to be as isolated as possible. Lining cabinet walls with mass loaded vinyl would be easy enough, but then you still need a solution for the doors.

Ultimately, the cabinet will need to be sealed off as much as possible because air leakage will also leak noise. At the same time, adequate airflow is necessary for longevity of components and their uptime.  

Usually air flows through the front of the rack, or a vented door and out of the back in the same manner. When sealing a rack, you need to design a mechanism for large amounts of air to flow through the rack while minimizing the amount of open space.  

Creating a rack with these features can be difficult depending on your experience level in engineering, woodworking or manufacturing.
